论文摘要
我们研究$ \ Mathcal {n} = 4 $ Sym Quark-Gluon等离子体的全息二元。为此，我们考虑Schwarzschild-$ ads_5 $和Kerr- $ ADS_5 $黑洞，这对于非旋转和旋转QGP是双重的。从临时威尔逊循环中，我们在两个背景中都发现了沉重的夸克电势。对于高于关键的温度，我们观察到电势的类似库仑样行为。我们发现增加旋转的间断距离降低，我们还看到温度的升高会产生相似的行为。此外，在高温下，kerr- $ ads_5 $的电势值接近Schwarzschild-$ ads_5 $ Black Hole中计算出来的。我们还探索了全息光明的威尔逊环路，从中从中提取了QGP中快速parton的喷射液压参数。我们发现旋转增加了喷射Quenching参数的值。然而，在高温下，喷射液压参数与广告黑色勃雷（Black Brane）的温度具有立方的依赖性。
We study Wilson loops in holographic duals of the $\mathcal{N}=4$ SYM quark-gluon plasma. For this we consider the Schwarzschild-$AdS_5$ and Kerr-$AdS_5$ black holes, which are dual to the non-rotating and rotating QGPs, correspondingly. From temporal Wilson loops we find the heavy quark potentials in both backgrounds. For the temperature above the critical one we observe the Coulomb-like behaviour of the potentials. We find that increasing the rotation the interquark distance decreases, we also see that the increase of the temperature yields the similar behaviour. Moreover, at high temperatures values of the potentials in Kerr-$AdS_5$ are close to that one calculated in the Schwarzschild-$AdS_5$ black hole. We also explore holographic light-like Wilson loops from which the jet-quenching parameters of a fast parton propagating in the QGP are extracted. We find that the rotation increases the value of the jet-quenching parameter. However, at high temperatures the jet-quenching parameters have a cubic dependence on the temperature as for the AdS black brane.
